For now, I am using a 2k Saturn texture for celestia.Sci that I made some years ago, when the blue Northern color became known via Cassini.

I also made my own 4k Saturn rings from the quite recent hires data by Cassini.

and here a detailed view of the high ring resolution:

Yet, notably the rings need further work, to reproduce their differing albedo, when looking from above and below the ringplane (!), respectively. A further independent requirement is to implement the correct transparency of the ring as function of the radial distance from Saturn's cloudy surface. In my case, the transparency is OK, as well as the one-sided albedo (top view). The strongly varying transparency profile of the Saturn ring was derived from hires stellar transit data taken from Earth!

the thumb nail links to a FULL sizer 4096x2048 image but there is a small version displayed first but if you click on it it shows the full size or if you just r-click and select save as it will be a 4k image

and that 6.3 meg "jvv.saturn2.png" on imagbox IS the same map i used and do use
